A procedural derive macro which exposes a method named all_values that returns all defined values as a compile-time static.
Add derive_enum_all_values to your Cargo.toml:
toml
[dependencies]
derive_enum_all_values = "0.1.0"
And then derive AllValues for your enum:
```rust use deriveenumall_values::AllValues;
enum MyEnum { Variant1, Variant2, // ... other variants ... }
fn main() { for variant in MyEnum::all_values() { println!("{:?}", variant); } } ```
This macro generates the following code:
rust
impl MyEnum {
pub fn all_values() -> &'static [MyEnum] {
&[MyEnum::Variant1, MyEnum::Variant2]
}
}
A static, compile time known array containing every enum value.
How to develop this project.
Clone this Repository: ```bash
git clone -c core.symlinks=true https://github.com/Sewer56/derive-enum-all-values.git ```
Install Rust: - Install the Rust Toolchain.Setup IDE - This repository is fully with VSCode. Guidance below.
Code/VSCode is the de-facto Rust development environment.
The following extensions are required:
- rust-analyzer for Rust support.
- coverage-gutters for Coverage support.
- CodeLLDB for debugging.
- crates easier dependency management.
The VSCode configuration in Reloaded projects (.vscode) contain the following:
- Run Rust linter clippy on Save.
- Run code format rustfmt on Save.
- Tasks for common operations (generate documentation, active CI/CD etc.).
These configurations are in the .vscode folder; and the tasks can be ran via Ctrl+Shift+P -> Run Task.
The following is the expected file layout for your project:
.vscode/
src/
Cargo.toml
The src folder should contains all source code for your project.
Cargo.toml should be in the root of the project.
